A pressurizing mechanism that elastically presses the thermal head 11 attached to the thermal head support plate 13 against a rubber platen 17 fixed to the rotation support shaft 21, one end of which is attached to a thermal head. A highly wear-resistant flexible cable 25 fixed to the head support plate is wound around the rotary support shaft of the platen at least by a predetermined angle, and the other end of the flexible cable is connected to the thermal head so as to reduce the contact pressure between the thermal head and the platen. A thermal head pressurizing mechanism for a thermal printer, characterized in that it is fixed to a part of the thermal printer other than the platen via a spring 27 that maintains a minute pressure close to zero. 2. The thermal head pressurizing mechanism for a thermal printer according to claim 1, wherein the other end of the flexible cable is fixed to the thermal head support plate via a spring.
